"" is an important skill to learn in order to maintain good posture. Good posture is essential to proper spine health and helps you to look confident and feel good. To achieve good posture when standing, it is important to engage certain muscles. The primary muscles to engage are the core muscles, glutes, and hamstrings. To engage the core muscles, tighten your abdominal muscles and draw your belly button in. To engage the glutes, squeeze your butt cheeks together and slightly tilt your pelvis forward. To engage the hamstrings, press your legs slightly outward and straighten your knees. Maintaining good posture when standing requires focus and muscle engagement. With practice and proper form, you can learn to stand up straight and stay in good posture for longer periods of time.
